Thoughts and the Old Drawing Board

This is the first entry into my new notebook that I found a few days ago:

I have decided that every fantasy author, in order to write a compelling and full story, must not only create a history behind everything (as suggested by a fellow author {Thanks Lauren!}), but also fashion the natural and supernatural laws behind the universe in which the story takes place. Tolkien did this in a small way, and he wrote that story in the Silmarillion. In his universe, there was Iluvatar, who created everything. He began with the Valar, his personal disciples. To them he taught the music, and they rejoiced in it. But one, Morgoth, fell away to make his own music. His music was ugly and discordant with the others. These beginnings shaped the world and the beings there, affecting and eventually causing the conflicts that became the Lord of the Rings trilogy. Once you know the beginning, combined with the laws, you can see where the events therein will lead, if the beginning and the laws are solid enough. So, we begin with the laws:
1) "There is a supreme being."
There always has to be some sort of direct or indirect manifestation of God, or else there wouldn't be any purpose to the story. Some sort of supreme being (preferably a greater good)must guide the hero(es) through the quest.
2) "There has to be an evil."
If you have God, you have to have Anti-God or else there wouldn't be a conflict.
2a) If there are good and evil, then there are certain properties inherent in the preconceptions of both. Evil has certain qualities that cannot be denied. At the base of these qualities are deception, temptation, and corruption. At the head of this is pride of course, but that is the source. Through all of these, evil tries to win the good to it's side.
3)"There is creation."
This is where the battleground between good and evil takes place.

These are the basic laws that govern fantasy worlds. After these are set down, others are set in place. You can show how that evil came to be, why it came to be, how the good came about a solution to the evil, how evil rose again, etc. You can get my drift, and I've spoken enough. I'll probably expand a little on these ideas later, probably more specific towards my story that I want to write.
